Is rank hack bannable?

Hey guys, this is my first post on the forum, i would like to say HI to everyone . Also, i have just a small question that i would like to be answered: is rank hack bannable??? Of what I heard, it is not, but I just want to make sure and ask for another opinion. I once got banned from MW2 and now I started playing again. Please answer me and thanks alot if you do

Also if you make you kills a lot higher than your deaths, you won't be able to find any games.
Oh yeah. Do all your stat editing before you get in a game. I did it on the main screen (Screen the game opens to) and it worked fine for me.
